Credit card sized USB flash drive

ABSTRACT

A flash memory mass storage drive stores user files in a convenient credit card sized drive. Embodiments function as both a credit card and a mass storage drive. Communication may be through a host interface connector such as a USB connector, a magnetic interface, a smart card interface, and/or a near field communication interface. In certain embodiments the drive comprises a portion that is sufficiently thin to be swiped through a standard credit card, ATM, or point of sale device. The USB connector of the drive can easily be plugged into even a crowded receptacle of a host computing device.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to and claims priority from U.S. ProvisionalPatent Application No. 60/745,813 to Gonzalez et al., filed Apr. 27,2006.

All patents, patent applications, articles, books, specifications, otherpublications, documents and things referenced herein are herebyincorporated herein by this reference in their entirety for allpurposes. To the extent of any inconsistency or conflict in thedefinition or use of a term between any of the incorporatedpublications, documents or things and the text of the present document,the definition or use of the term in the present document shall prevail.

FIELD OF THE INVENTION

The present application is generally related to portable flash memorybased mass storage devices and credit cards.

BACKGROUND

A digital savvy consumer is accustomed to having files at the readywherever he goes, and doing so without having to carry a large hostdevice such as a digital camera, cellular telephone or astandard/dedicated memory card or USB flash drive would be quiteconvenient.

SUMMARY

The great majority of consumers almost always carry a credit card.Therefore, it provides a convenient medium for storing user files.However, the standard credit card is quite thin and incorporating theflash memory hardware and the connectors in a thin and convenientpackage that consumers will readily adopt is a challenge.

Embodiments of the present invention act as a hard drive with a creditcard like size, conveniently transported in a wallet or purse along withother identification cards, automatic teller cards, credit cards and thelike.

Some embodiments may also be read by a credit card reader, and thereforecomprise a portion, with a magnetic stripe, thin enough to slide througha standard credit card reader. This results in a truly multi-purposedevice in areas where the magnetic stripe is the accepted medium forcarrying out transactions, such as the United States. In other countrieswhere a Smart Card contact pattern is the accepted communication medium,a thin card is also dictated, and the contact pattern would therefore bepresent on a portion of the device thin enough to be read by commercialcard readers at Smart Card point of sale locations and teller machinesetc.

Certain embodiments incorporate a double axis hinge that convenientlycovers the connector used to communicate with a host device while not itis not in use. The cover carried by the card is rotatable by handbetween at least first and second positions about an axis extendingacross a width of the card, the contacts being covered when the cover isin the first position and exposed for insertion into a female receptacleof a host when the cover is in the second position.

Other embodiments include a member with the USB connector at the freethat slides and/or pivots to enable insertion.

Yet other embodiments include a member that may be physically removedfor insertion, or that remains connected but can be ejected or rotatedto be coupled with a host device.

Yet other embodiments utilize a flexible material or substrate in thebody of the card that can be bent so that either part of the card bodyor part of the member bends in order to facilitate coupling with thehost device.

Communications for purposes of mass storage and for carrying outtransactions can also be made without plugging the drive in, throughnear field communications circuitry provided in the device. The devicemay also communicate via a magnetic stripe interface, Smart Cardinterface, or through the contacts of a male connector that physicallyplugs into a female receptacle of the host device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention comprises a flash memory based mass storage drivehaving the length and width of a credit card, so that it may easily fitin a wallet. Some preferred embodiments of the card include a body whereat least some portion of the body has a thickness of a standard creditcard so that a magnetic stripe or Smart Card interface contacts locatedat that portion can be easily run through a standard credit card reader(including an ATM) or other point of sale (“POS”) device. This thicknessof the CCFD may vary depending on the credit card reader's ability toaccept cards of varying thickness. In some embodiments, the thickness ofthe CCFD is substantially uniform, whereas in some other embodiments,some portion of the card may be thicker than another portion of thecard. In such a case, the thicker portion or portions may be where theelectronic components and/or connector are located.

While it is desirable to have the body of the CCFD relatively thin, forexample, the thickness of a standard credit card (approx. 0.8 mm), inembodiments of the drive incorporating a type A USB connector, theconnector, even without a shield, must be somewhat thicker (approx. 1.7mm) than a standard credit card in order for the connector to seatproperly in a USB socket and for the contacts of the drive to makeproper contact with the contacts of a host receptacle.

A USB flash drive comprises a mass storage flash memory, which may becomprised of one or more integrated circuit die. As a credit card formfactor has a large surface area, the integrated circuit die can bedistributed over the area of the card. In such an embodiment theintegrated circuit die need not be stacked, and the thickness of thecredit card can be minimized. Alternatively, the integrated circuit diecan be located in a centralized area. That area may be near the hostconnector (which is preferably a USB connector) and/or on a moveablemember that also comprises the connector. All or a portion of the membercan be as thick as required for proper seating in a USB receptacle. Insuch a case, the die may be stacked if necessary as the thicker portionof the card/member will easily accommodate the height of the stackeddie.

The following figures illustrate different embodiments of the presentinvention. Different aspects of the embodiments may be interchanged withother of the embodiments.

FIG. 1C is a block diagram of the main components of a CCFD. The creditcard flash drive comprises a memory controller 152 that controlsread/write operations to/from the mass storage flash memory 158. Thememory controller is coupled to the host interface connector 160 andalso serves to control the data transfer to/from a host device when thedrive is plugged into the host 170. The host interface is preferably aUSB interface and the host interface connector 160 is thus one of themany types of available USB connectors. Other types of host interfaceconnections such as IEE1394 (a.k.a. Firewire) or other high speed typeconnectors/interfaces may also be used. In some embodiments, the drivealso comprises near field communications (“NFC”) capability including anNFC controller 154 and NFC antenna 156. In certain embodiments, the NFCcontroller is eliminated and the functionality integrated into memorycontroller 152. The NFC antenna communicates with NFC point of saledevice 176 to execute transactions, and may also communicate datato/from host 170 in lieu of using physical connector 160.

Some embodiments may also comprise a Smart Card interface 162 forcommunicating with a Smart Card enabled POS device 172. The Smart Cardinterface is preferably controlled by memory controller 152, but aseparate Smart Card controller (not shown) may instead be integratedinto the drive. While the data transfer rate/methodology specified bythe Smart Card specification is generally considered inadequate for massdata transfer, the Smart Card interface is desirable because it enablesuse with Smart Card readers and thus allows for transactions in thenumerous establishments equipped with such readers. Magnetic interface(“MI”) 106, typically a standard credit card magnetic stripe, isprovided to interface and carry out transactions with magnetic interfacePOS systems 174. MI 106 may be self contained or may interface withmemory controller 152 for storing and retrieving transactional data inand from flash memory 158. For more information on integration of aSmart Card controller in the mass storage drive and for NFCcommunications, please refer to application Ser. No. 11/321,833 entitled“Methods Used in a Nested Memory System With Near Field CommunicationsCapability.” MI 106 is preferably on a portion of the drive thin enoughto be read by a standard credit card/ATM reader, as are the contacts ofSmart Card interface (“SCI”) 162. For simplicity, the contacts of theSmart Card interface will not be shown in various views of the drives,but may be present at a sufficiently thin portion of the drive,typically near where MI 106 is shown. For more information on the smartcard contacts please refer to the ISO 7816 standards which have beenincorporated by reference in the entirety. When the CCFD is connectedwith a host device, and the host is connected to the Internet, financialand user identity data stored in the flash memory may be transmitted toprocessing entities to facilitate transactions. This is in addition toin conjunction with standard credit card transaction processing datatransmitted via MI 106 and/or SCI 162, and/or the NFC hardware.

FIGS. 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B, 4C, 5A, 5B, 5C, 6A, 6B, 6C, 7, 7A,8, 8A, 9, 10A, 10B, 11A, 11B, 12A, 12B, 13A, and 13B are different viewsof hinged embodiments of a CCFD.

Referring to the figures, an example CCFD will be described. Apredominately rectangular main body portion 11, having the length andwidth of a credit card (approximately 84 mm×54 mm) has a rectangularextension 13 formed as part of the card to provide an interface for themass storage of data, in this case a USB compatible plug. Since theextension 13 is narrower than the portion 11, end surfaces 12 and 14 ofthe main body portion 11 exist on either side of the extension 13. Fourelectrical contacts 37-40, arranged according to the USB specifications,are provided on the flat surface of the extension 13.

In order to protect the contacts 37-40 when not being used, a cover 43is rotatably connected with the card so that it may be closed to coverthe contacts 37-40 when they are not being used (the position of FIGS.1A, 2A and 3A) and opened to expose the contacts 37-40 when theextension 13 is inserted into a mating receptacle (the position of FIGS.1B, 2B and 3C). These positions are shown to be one hundred eightydegrees apart. In this specific example, the cover 43 is attached to thecard portion 11 at its end surfaces 12 and 14 by respective hinges 45and 47 that allow for such rotation of the cover 43 by hand. The cover43 has thick side portions 49 and 51 to which the hinges 45 and 47 arerespectively connected. The side portions 49 and 51 fit around theextension 13 when the cover is closed, and a thin layer 53 of materialspanning between the side portions 49 and 51 covers the contacts whenthe cover 43 is closed. The layer 53 has a size that is approximatelythat of the extension 13 in order to cover it when the cover 43 isclosed. An end portion 55 spanning the side portions 49 and 51 is alsopreferably provided as part of the cover 43. When the cover 43 isclosed, its end portion 55 fits over an extreme end of the extension 13.

In order to be compatible with the USB specifications, the addition 13has a minimum length of 12 mm. from the ends 12 and 14 of the main bodyportion 11 and has a width of 12.35 mm. The main body portion 11 of thememory card of FIGS. 1A and 1B, in this specific example, is about thewidth of a standard credit card, which is about 54 mm. The thickness mayvary in the different embodiments. These dimensions may vary from thosestated, if a non standard credit card or USB plug is desired. Also,different styles of USB plugs may be utilized. For example, a smallerUSB plug may be utilized. For details on the various types of USB plugsand receptacles, and other information relating to the USB standard,please refer to the “Universal Serial Bus Specification” revision 2.0,dated Apr. 27, 2000 which is hereby incorporated by reference in theentirety.

The cover 43 is made to have the same outside width of 54 mm. and itsside portions 49 and 51 the same thickness as the card portion 11. Theextension 13 has a thickness 43 of 1.70 mm. in the region of thecontacts 37-40, according to the USB specifications.

In order to hold the cover closed, a latch 57 may be provided on theinside of one or both of the side portions 49 and 51 of the cover 43 tosnap into mating receptacle(s) (not shown) on the side walls of theextension 13. When the cover 43 is closed, the CCFD can be stored in awallet or elsewhere without worry of damaging the contacts.

Although the cover is shown to be same width as the card portion 11, andthe extension 13 is shown to be in the middle of the short side of thecard, both the location of the extension and the size of the cover mayvary. For example, rather than being located in the middle of the shortside of the card, the extension 13 may be offset some amount from thecenterline. In such a case, the cover 43 may still have the same widthas main portion 11, or may have a smaller width. In such a case the mainportion 11 may have an “L” shape rather than a rectangular shape, with aportion of the L having the full length of a credit card, with amagnetic stripe (shown in the embodiments of FIGS. 10-13) on asufficiently thin portion suitable to be swiped and read by a creditcard reader. As mentioned previously, a Smart Card contactpattern/interface may also be provided on suitably thin portion of thedrive. Alternatively, the extension 13 and cover 43 may be aligned 90degrees from that shown in the figures. Alternatively, they may bealigned so that extension 13 and cover 43 have an alignment notorthogonal to either the length or width of the card.

An appropriate latch (not shown) may additionally be included to holdthe cover 43 in its opened position.

Again, while the USB connector is currently preferable, preferences tendto change, and other standards for the connector may be utilized. Forexample, the IEEE 1394 standard could be used instead, or an undevelopedstandard could be implemented.

The specific hinges 45 and 47 shown in the example CCFD of the figuresare sometimes called “dog bone” hinges. They are of rigid material. Oneend of each of these elongated hinges is attached to the CCFD portion 11to rotate about an axis 61 that extends across the width of the cardthrough its main portion 11. Another end of each of the hinges 45 and 47is attached to the cover 43 to rotate about an axis 63 that extendsacross the width of the cover 43. Both of the axes of rotation 61 and 63are stationary with respect to their respective CCFD portion 11 andcover 43. During movement of the cover between its opened and closedpositions, the axis 63 moves normal to the memory card to allow thecover 43 to adjust between the different levels of the CCFD's topsurface. It will also be noted from the views of FIGS. 3A-3C that themating edges of the cover 43 and main CCFD portion 11 are curved toallow smooth motion between them as the cover 43 is moved by handbetween its open and closed positions. The axis 63 also moves laterallyalong the length of the memory card as the cover is being opened orclosed.

This hinge structure can also be modified to provide a detent that holdsthe cover 43 in its closed position (FIG. 3A), in place of the latch 57(FIG. 1B), and in its opened position (FIG. 3C). One way to do so is tosquare off the ends of the rigid hinges 45 and 47 and provide matingrectangular receptacles in the card portion 11 and cover 43 that latchthe cover at 0° and 90° with respect to the hinges but allows freerotation between those positions. An alternate structure replaces therounded edges of the CCFD portion 11 and the cover 43 with substantiallysquare surfaces, and the hinges 45 and 47 are provided some degree ofelasticity so that they pull these planar edges together when the cover43 is closed. As the cover is then opened by hand, the hinges stretch toallow the edge of the cover to rotate over the edge of the CCFD portion11 and then pull the cover and body together again after the cover hasbeen rotated into its opened position.

Other alternatives to this specific hinge structure can certainly beused, so long as the cover 43 is rotatable by hand with respect to thecard portions 11 and 13 about one or more axes extending across thewidth of the card. A different type of solid mechanical hinge can beused, for example. Or something altogether different can be used. Aflexible member adhered to the cover and the main CCFD portion 11, forexample, may be substituted for the mechanical hinges. An example of theflexible member is polyimide film bonded or welded to the pieces.

FIGS. 4A-28 show embodiments of a CCFD that implements certain aspectsof the CCFD designs described above. Elements of the embodiments thatcorrespond with elements of FIGS. 1A-10B described above are thereforeidentified with the same reference numbers but with a prime (′) added.Many of these corresponding elements are therefore not described again,in which case the prior descriptions of the elements are incorporatedinto the following description.

A main body portion 11′ of the CCFD of FIGS. 4A-13B has a cover 43′attached to the body 11′ by solid, rigid hinges 45′ and 47′ that havethe same shape. The cover 43′ is rotatable with respect to the body 11′over a range of substantially 180 degrees between closed (FIG. 4A) andopened (FIG. 4C) positions. The relative dimensions of the body 11′ andcover 43′ are such that the cover overlies a portion of the cardcontacts 15′-23′ when the cover is opened (FIG. 4C). A USB plugextension 13′ is exposed for use when the cover is opened. When thecover is closed (FIG. 4A), the CCFD has the outline of credit card andsome embodiments can be used as a credit card.

The shapes of the hinges and mating surfaces of the card body and coverprovide three stable positions of the cover: closed (FIG. 4A), opened(FIG. 4C) and an optional intermediate position (FIG. 4B). The cover islatched into one of these stable positions by a user manipulating theparts with his or her fingers. They are separated by substantially 90degrees. The latching may be overcome by gentle finger force thatrotates the cover out of any one of these stable positions. Althoughthis is, in this example, the only mechanism that holds the cover fullyopened (FIG. 4C), a more positive latch is also included to hold thecover closed (FIG. 4A). As best shown in FIG. 9, a lip 71 is provided onan underside of the cover 43′ that flexes outward around the extension13′ as the cover is closed to positively latch the extension 13′ whenthe cover reaches the position shown.

A layer 53′ across the cover is preferably provided with indentations73-76 having positions and shapes that match electrical contacts 37′-40′raised above a surface of the extension 13′. When the cover is closed(FIG. 4A), the contacts fit within these indentations to allow the coverlayer 53′ to abut against surface area of the extension 13′ surroundingthe contacts 37′-40′.

The structure and operation of the hinge 47′ will now be described. Thestructure and operation of the hinge 45′ is the same. A slot 79 extendscompletely through the body 11′ for a distance from its edge where thehinge 47′ is held. Similarly, a slot 81 goes all the way through thecover 43′ for a distance from an edge that retains the hinge 47′. Thehinge 47′ is held within these slots. These slots form respective strips86 and 88 that flex outward as the hinge 47′ is rotated with respect tothe respective body 11′ and cover 43′ between the three stablepositions, thereby expanding the width of the slots 79 and 81. Thestrips 86 and 88 resiliently return to their rest positions when thecover is in one of the three stable positions shown in FIGS. 4A, 4B and4C, urging against the hinge 47′.

The structure and operation of the hinge 47′ may best be explained byreference to the exploded views of FIGS. 6A, 6B and 6C that showrelative positions of the parts when the cover is in the closed,intermediate and opened positions of respective FIGS. 4A, 4B and 4C. Thehinge 47′ is a solid plastic piece with first and second cylindricalaxles 81 and 83 that each extend out of opposite sides of the part andare spaced apart along its length. The hinge 47′ therefore rotates aboutaxes 82 and 84 of the respective axles. A pattern of ridges 85, 87 and89 protrude out from a planar surface 91 on one side. The structure onthe opposite side is the same. The ridge 85 extends along the length ofthe hinge 47′ through both of the axles 81 and 83. The ridges 87 and 89extend across the width of the hinge through one of the axles 81 and 83,respectively, perpendicular to the ridge 85. In cross-section, theridges are narrower at their tops than at their bottoms where theyintersect the hinge surface 91. In this example, their sidewalls arealso planar and intersect top planar surfaces of the ridges and thehinge surface 91 with a common angle other than ninety degrees.

Surfaces of the body 11′ and cover 43′ that engage the sides of thehinge 47′ have a complementarily shape. The surfaces that engage oneside of the hinge 47′ are shown in FIGS. 6A, 6B and 6C. A cylindricallyshaped hole 95 on the main body 11′ receives one end of the axle 81 onthe backside of the hinge 47′ in a manner that allows the axle to rotatewith respect thereto. Similarly, the cover 43′ includes a cylindricallyshaped hole 97 into which one end of the axle 83 is inserted to rotatewith respect to the cover. The body 11′ includes channels 99 and 101that extend through the opening 95 and are perpendicular with eachother. Similarly, channels 103 and 105 pass through the opening 97 ofthe cover 43′ and are perpendicular with each other. In cross-section,the channels 99, 101, 103 and 105 are the same along their lengths andmate with the common shaped ridges 85, 87 and 89 of the hinge 47′. Inthis example, the channels have planar bottom surfaces that are narrowerthan the widths of their openings, and their sidewalls are also planar.The sidewalls therefore intersect the bottom surface of the grooves anda planar surface surrounding the grooves with angles that are other thanninety degrees.

Operation of the hinge 47′ when the cover 43′ is opened or closed canbest be seen by comparing the views of FIGS. 6A, 6B and 6C. FIG. 6Ashows the relative position of the parts when the cover is closed (seeFIG. 4A). The ridge 85 on the opposite side of the hinge 47′ ispositioned in the channels 99 and 105 of the body 11′ and cover 43′,respectively. The ridge 87 on the opposite side of the hinge ispositioned in the channel 101 of the body 11′, and the ridge 89 in thechannel 105 of the cover 43′

As the cover is opened, the hinge 47′ does not move with respect to thecover 43′ but does rotate about the axis 82 with respect to the body11′. As the cover begins to rotate, the ridges 85 and 87 of the hinge47′ move out of the respective channels 99 and 101 of the body 11′. Thisis possible since the strip 86 is resiliently movable to the side awayfrom the hinge. The mating sloping sides of the ridges and channelscauses a caming action that pushes against the resiliently loaded strip86 as the ridges are forced out of the channels. When the cover has beenrotated ninety degrees to the intermediate position of FIG. 4B, thehinge and cooperating surfaces are caused to again engage each otherbecause of the resilience of the strip 86 urging them together. Theparts are then in the relative positions shown in FIG. 6B. The ridge 85is then positioned within the channel 101 of the body 11′ and the ridge87 in the channel 101. The body 11′ has not moved but the cover 43′ andthe hinge 47′, which remain locked together, have rotated ninety degreesabout the axis 82 with respect to the body 11′.

Further rotation of the cover 43′ moves the parts to their relativepositions shown in FIG. 6C, where the cover is fully opened (see FIG.4C). The hinge 87′ remains locked to the body 11′ as the cover 43′ isrotated ninety degrees with respect to the hinge 47′ about the axis 84.At the beginning of this rotation, the ridges of the hinge move out ofthe channels of the cover by the cam action that urges the strip 88laterally away from the hinge. After the cover is rotated ninetydegrees, the ridges 85 and 89 of the hinge 47′ are urged into therespective channels 105 and 103 of the cover 43′, the position shown inFIG. 6C.

It will be noted that the ridge 87 of the hinge 47′ and a portion of theridge 85 adjacent to it mate with the channels 99 and 101 of the cardbody 11′. If the hinge were free to rotate a full 360 degrees, thesemating surface relief patterns would provide four stable rotationalpositions 90 degrees from each other about the first axis 82. Similarly,the ridge 89 and portion of the ridge 85 adjacent to it that mate withthe channels 103 and 105 of the cover provide four similar stablerotatable positions between the hinges and the cover about the secondaxis 84. The mechanism is constrained, however, in this example, toutilize only two rotatable positions with the body 11′ and two rotatablepositions with the cover 43′. This combination provides the three stablerotatable positions between the cover and the card body that areillustrated in FIGS. 4A, 4B and 4C.

Although not explicitly shown, the second opposite surface of the hinge47′ is urged against opposing surfaces of the body and cover having thesame shapes as those shown in FIGS. 6A, 6B and 6C. The hinge and theseother surfaces cooperate in the same manner as described above.

FIGS. 5A, 5B and 5C have not been discussed but it may be noted thatthey show relative orientations of the hinge 47′ for the positions ofthe covers shown in respective FIGS. 4A, 4B and 4C. FIGS. 10A, 10B, 11A,11B, 12A, 12B, 13A, and 13B are different views of an embodiment similarto that previously described but having a relatively thinner portionsuitable to be swiped through a credit card reader.

FIGS. 14A-B illustrate a pivot embodiment of a CCFD. The drive in FIG.14 has a member 114 that rotates or pivots about axis 118. There existsa thin portion 102 and a thicker portion 110. At the end of member 114distal to axis of rotation or pivot point 118, are the contacts of theUSB connector (not shown). The distal portion of member 114 isdimensionally and functionally the same or similar to extension 13 and13′ described earlier and contains the same arrangement of USB contacts.A pocket or sleeve 122 accommodates member 114 for transport or storage.When a user wishes to the plug the drive into a host computer, the usermay grip member 114 at cutout 126 and rotate member 114 out of thepocket 122. The pivot allows for 180 degrees or more of rotation, andthe long length of the member facilitates insertion into a USB port thatmay be crowded by other connectors on the back of a host device such asa PC.

It can be seen that in the embodiments shown in FIGS. 10-28 there is amagnetic interface or stripe 106 on a surface of the card. This magneticstripe is typical of the kind used in credit and ATM cards. It islocated on a portion 102 of the card thin enough to be read by astandard swipe through type credit/ATM card reader. As mentionedearlier, a Smart Card interface/contact pattern (not shown) may also bepresent in portion 102.

FIGS. 15A-B illustrate a flexible tether embodiment of a CCFD. In FIG.15, the member 114′ also pivots about an axis 118′ near the corner ofthe card, however the member includes a flexible portion 116 that actsas a tether. The pivoting about axis 118′ may be achieved with arotating hinge similar to that seen in FIG. 10, and may also rely on theflexibility of portion 116. This flexible portion 116 may stretch,rotate, and bend in any number of ways so that the connector can beeasily inserted into a USB port. In one embodiment, the member isco-molded and the tether is flexible rubber, whereas the connectorportion is of a less flexible material. In FIG. 15, the member rotatesabout a moveable axis. The axis of rotation can slide or translate alongthe long axis of the card, and thus the member can both slide and pivot.Again, this facilitates insertion into USB receptacles that mayotherwise be difficult or impossible to access.

FIGS. 16A-B illustrate a slide and pivot embodiment of a CCFD. In thisembodiment, the axis of rotation 118 translates or slide along axis 120.This allows for a greater range of movement and flexibility forinsertion into what may be crowded (USB) host receptacles.

FIG. 17 illustrates a holder type embodiment of a CCFD. In FIG. 17 themember can be removed from the card for insertion purposes. A connector(not shown) between the member 114′ and the body of the card allows anydata stored in the member to be communicated back to components on thebody, including Smart Card contacts/interface, the magnetic stripe, orany other of the electronic components previously described. Member 114′has a female semi-cylindrical groove 119 that slides onto a male semicylindrical portion 117 of the body of the drive. When a user wishes toplug member 114′ into the host, he will slide member 114 off of semicylindrical retaining portion 117. The male and female connectingportions may alternatively be gender reversed and of different geometry.USB contacts 37′-40′ are also shown.

FIG. 17 illustrates another holder type embodiment of a CCFD. Thisembodiment also includes a removable member 114′ in an open “pocket” ofthe body. Tabs 104 can be manipulated to insert or remove member 114,which is otherwise securely held in place.

FIGS. 19-21 illustrate other holder type embodiments where the membermay be removed. In the embodiment of FIG. 19, a push-push (springloaded) type connector may be implemented such that one push of thedistal end brings the member out and another push puts it away. Button130 may alternatively be used to eject member 114′. Member 114′ may alsobe completely removable in the embodiment of FIG. 19. In FIG. 20, thebody of the drive is flexible and a user can bend each side to removemember 114′.

In FIG. 21 a detent stops the member from being removed past a certainpoint, although the detent may be overcome with sufficient pressure.Member 114′ of FIG. 21 may be spring loaded or manually pushed with theribs of the member.

FIG. 22 illustrates another pivot embodiment of a CCFD. In thisembodiment there is no pocket or sleeve, and the member is at theshorter of the sides of the drive.

FIG. 23 illustrates a living hinge embodiment of a CCFD. In thisembodiment, the flexible portion 136, that ties member 114′ to the bodyof the drive, which may also be referred to as a living hinge, allowsthe member to be either flat within the body for insertion in a wallet,or extended away from the body for insertion into a USB port. Theflexible living hinge 136 may be bent so that the member 114′ may beremoved from under tab 104′ and then the distal end of member 114′ canbe extended away from the body and inserted into the host connector. Thebody and member may be made of one material or a combination ofdifferent materials with different moduli of elasticity.

FIG. 24 illustrates a sliding embodiment of a CCFD. In this embodiment,the member can be pushed in and out of the body. This may be manual orspring loaded.

FIG. 25 illustrates a slide and turn embodiment of a CCFD. In thisembodiment the member has an arcuate portion and travels along an arcduring extension and retraction. A hole 132 for a key ring may also beincluded.

FIG. 26 illustrates a hinged embodiment of a CCFD. In this case, thehinge is at an end of the card, and the member can be nearly as long asthe card itself. It can also, of course, be any length less than thelength of the card. A catch 140 is also included to keep the membersubstantially parallel to the card for storage and transport.

FIG. 27 illustrates another pivot embodiment of a CCFD. In this case thepivot is centrally located on the long side of the card and the membercan rotate out. Alternatively, the member can have a short cable/tetherand be removed from its pocket while still electronically connected toother components on the body of the card.

FIG. 28 illustrates an embodiment of a CCFD similar to that of FIGS.13A-B, but with the removable member 114′ on the short side of thedrive. The member 114′ slides on a cylindrical rod of the body of thecard.

FIGS. 29A-27B illustrate embodiments with a portion of the body of thedrive made of a flexible material (e.g. a polymer, rubber, and/orcomposite) that allows sufficient bending of the credit card such thatthe USB plug at the end of member 114′ can be distanced sufficientlyfrom the body of the drive to be inserted into the host by bending of aportion of the drive.

FIGS. 29A and 29B are a bottom view of such a drive. A type of latch orclip 140′ retains the distal end of member 114′ and thus maintains thebody and overall drive in a flat or unfolded position, as seen in FIG.29A. In FIG. 29B, a portion of the body of the drive is bent at an area142 between latch 140′ where the proximal end of the member 114′ isattached to the thicker area 110′ of the body of the drive. FIG. 29D isa top view with the drive folded/bent to expose contacts 37′-40′.

FIGS. 30A and 30B illustrate the same embodiment of FIGS. 29A-D with theaddition of NFC antenna 156. FIG. 30A is a top view looking through thedrive. Antenna 156 is connected to member 114′ by solder or conductiveglue attach. FIG. 30B is also a top view looking through the drive, butin FIG. 30B, the drive is folded or bent to make insertion of the USBconnector portion of member 114′.

FIGS. 31A and 31B illustrate an embodiment identical to that of FIGS.30A-B but with a larger antenna 156′ that encircles member 114′. Thedrive can be seen bent an area 142′ such that it is nearly foldedentirely back upon itself.

FIG. 32 illustrates an embodiment where member 114′ slides within recess182 of thicker portion 110 and is held in place under flaps 180. Member114′ and recess 182 may incorporate detents or a latching mechanism thataids in keeping member 114′ in place. Member 114′ may optionally slideaway from the body on rails (not shown) and may in some cases betethered to the body with a metal wire or wires. The metal wires maytransfer data between the components in the member and in the body.

Note that in embodiments depicted with a varying thickness, thethickness may be uniform rather than varied, as mentioned previously.Additionally, the MI 106 need not necessarily be present in the variousembodiments, although it is frequently shown for illustrative purposes.Additionally, although a type “A” USB connector has been depicted anddescribed in many of the embodiments, a type “B,” mini USB or other typeUSB connector may be utilized. Interfaces and connectors other than aUSB type may also be used, as mentioned previously.
